Luckily, the solution is quite simple, we just need to remove the protection attribute using chattr. Run the following as root to remove the attribute on 60-net.rules preventing us from updating initscripts:

chattr -i /usr/lib/udev/rules.d/60-net.rules

That's it, try running yum update once more and the program will be updated without issue now.

Again, if you are irritated with fact that cPanel/WHM decided to disable EA3 in new installs, the solution is before starting with 'sh latest' create the /etc/installlegacyea3insteadof_ea4 file, and repeat 'sh latest' again.
